Digital audio broadcasting

Digital audio broadcasting (DAB) is
an innovative and universal
broadcasting system.
Advantages of DAB
■ DAB stations are indicated by the
programme name instead of the
broadcasting frequency.
■ With DAB, several radio
programmes (services) can be
broadcasted on a single frequency
(ensemble).
■ Besides high-quality digital audio
services, DAB is also able to
transmit programme-associated
data and a multitude of other data
services including travel and traffic
information.
■ As long as a given DAB receiver
can pick up the signal sent out by a
broadcasting station (even if the
signal is very weak), sound
reproduction is ensured.
■ There is no fading (weakening of
the sound that is typical of AM or
FM reception). The DAB signal is
reproduced at a constant volume.
If the DAB signal is too weak to be
picked up by the receiver, reception
is interrupted completely. This can
be avoided by activating DAB to
DAB Linking and/or DAB to FM
Linking in the DAB option menu
(see below).
■ Interference caused by stations
that are on nearby frequencies (a
phenomenon that is typical of AM
and FM reception) does not occur
with DAB.
■ If the DAB signal is reflected by
natural obstacles or buildings, the
reception quality of DAB is
improved, whereas AM or FM
reception is considerably impaired
in such cases.
■ When DAB reception is enabled,
the FM tuner of the Infotainment
system remains active in the
background and continually
searches for the best receivable FM
stations. If TP 3 47 is activated,
traffic announcements of the FM
station which is currently best
